Helping practices reach primary care goals. Lessons from the literature.

We reviewed rigorous evaluations of programs to enhance the quality and economy of primary care. We identified 36 evaluations published from 1980 through 1992. We abstracted data on objectives, setting(s), patients and processes, outcomes, and costs of care. We identified successful programs, as well as significant gaps in our knowledge of how to improve aspects of care. In specific, computer reminders and social influence-based methods fostered preventive and economic care. Nurse implementation of prevention protocols increased their performance. Multidisciplinary teams improved access and economy. Regional organization of practices or telephone management improved access; regionalization also reduced emergency care. Improvements were not found in continuity, comprehensiveness, humanistic process, physical environment, or health outcomes. Primary care practices can implement several programs to continuously improve prevention and access, and to reduce costs and use of unnecessary services. Research documenting how to accomplish other major goals, including health outcome changes, in different practice types is needed.

Value of functional status as a predictor of mortality: results of a prospective study.

PURPOSE: To assess the value of functional status questions in predicting mortality, we conducted a 4-year prospective longitudinal follow-up study of functionally impaired community-dwelling elderly persons. SUBJECTS AND METHODS: A total of 282 elderly (aged 64 years or older) patients of 76 community-based physicians who were UCLA clinical faculty members were assessed at baseline and at an average of 51 months later using scales from the Functional Status Questionnaire. RESULTS: By the end of the study, 24% of the sample had died. By means of a multivariate model, the following baseline characteristics were independently predictive of death: greater dysfunction on a scale of intermediate activities of daily living, male gender, living alone, white race, better quality of social interactions, and age. Initial baseline functional measures were also predictive of follow-up health status perceptions. CONCLUSION: The assessment of information on physical functioning and the quality of social interactions provides prognostic information regarding mortality. Furthermore, of the independent predictors of death identified in this sample, only functional impairment and living alone are remediable. Whether improving functional status can reduce the risk of mortality remains to be determined.

Physician implementation of and patient adherence to recommendations from comprehensive geriatric assessment.

PURPOSE: The goals of this study were to develop and determine the feasibility of interventions designed to increase both primary care physician implementation of and patient adherence to recommendations from ambulatory-based consultative comprehensive geriatric assessment (CGA), and to identify sociodemographic and intervention-related predictors of physician and patient adherence. PATIENTS AND METHODS: One hundred thirty-nine community-dwelling older persons who failed a screen for functional impairment, depressive symptoms, falls, or urinary incontinence received outpatient CGA consultation. These patients and the 115 physicians who provided primary care for them received one of three adherence interventions, each of which had a physician education component and a patient education and empowerment component. Recommendations were classified as physician-initiated or self-care and as "major" or "minor"; one was deemed "most important". Adherence rates were determined on the basis of face-to-face interviews with patients. RESULTS: Based on 528 recommendations for 139 subjects, physician implementation of "most important" recommendations was 83% and of major recommendations was 78.5%. Patient adherence with physician-initiated "most important" and "major" recommendations were 81.8% and 78.8% respectively. In multivariate models, only the status of the recommendation of "most important" (odds ratio 2.4, 95% CI [confidence interval] 1.3 to 4.5) and health maintenance organization (HMO) status of the patient (odds ratio 2.1, 95% CI 1.3 to 3.6) remained significant in predicting physician implementation. The logistic model predicting patient adherence to physician-initiated recommendations included male patient gender (odds ratio 3.1, 95% CI 1.3 to 7.0), the status of the recommendation of "most important" (odds ratio 1.9, 95% CI 1.0 to 3.8), total number of recommendations (odds ratio 0.7, 95% CI 0.5 to 0.9), and total number of problems identified by CGA (odds ratio 1.8, 95% CI 1.2 to 2.7). CONCLUSIONS: These findings indicate that relatively modest interventions strategies are feasible and lead to high levels of physician implementation of and patient adherence to physician-initiated CGA recommendations. These interventions appear to be particularly effective in HMO patients and for recommendations that were deemed to be "most important".

Candidates for the Certificate of Added Qualifications in Geriatric Medicine. Who, why, and when?

We surveyed physicians who took the examination for certification for Added Qualifications in Geriatric Medicine, physicians who only inquired about the examination, and physicians who expressed no interest in the examination to learn about practice characteristics of those who took the examination and their reasons for taking it. Based on a 72% response rate, we were able to demonstrate that those who took the examination took care of an older population of patients and disproportionately more of the oldest-old. These physicians were more likely to report the care of older people to be a professional focus and, in internal medicine, were more likely to have had formal training in geriatrics. Their reasons for taking the examination were primarily to obtain credentials but also frequently to improve their ability to care for older people. Nearly two-thirds of those who had inquired about the exam but did not take it in 1988 plan to do so at a later date.

Managing geriatric syndromes: what geriatric assessment teams recommend, what primary care physicians implement, what patients adhere to.

OBJECTIVES: To evaluate the responses of primary care physicians and patients to recommendations from a community-based comprehensive geriatric assessment (CGA) program for management of four target conditions: falls, depression, urinary incontinence, and functional impairment. DESIGN: Case series. SETTING: Senior centers, meal sites, senior housing, and other community sites as screening locations; and a community-bases academic practice as the location for CGA. PARTICIPANTS: A total of 150 older patients living in the community who have one or more of the four target conditions and who received CGA. MEASUREMENTS: Physician implementation and patient adherence rates were ascertained during a face-to-face structured interview with the patient 3 months after CGA. RESULTS: Two hundred twelve of 528 (40%) CGA recommendations were clearly or possible related to the target or target-related conditions. Of these 212 recommendations, 59% required a physician's order for implementation. The remaining 41% were patient self-care recommendations. Overall physician implementation across conditions was 70%; implementation rates were highest for falls and lowest for functional impairment. Overall patient adherence rate was 85% for physician-implemented recommendations and 46% for self-care recommendations. Patient adherence to recommendations for counseling or support groups and exercise programs was particularly low. CONCLUSIONS: When examining the process of care of community-based CGA, patient as well as physician adherence must be considered. Although patient adherence to physician-initiated recommendations was high for all conditions, it varied substantially across target conditions and types of recommendations for self-care recommendations.

A randomized clinical trial of outpatient comprehensive geriatric assessment coupled with an intervention to increase adherence to recommendations.

BACKGROUND: Although comprehensive geriatric assessment (CGA) has been demonstrated to confer health benefits in some settings, its value in outpatient or office settings is uncertain. OBJECTIVE: To assess the effectiveness of outpatient CGA consultation coupled with an adherence intervention on 15-month health outcomes. DESIGN: A randomized controlled trial. SETTING: Community-based sites. PATIENTS: 363 community-dwelling older persons who had failed a screen for at least one of four conditions (falls, urinary incontinence, depressive symptoms, or functional impairment) INTERVENTION: A single outpatient CGA consultation coupled with an intervention to improve primary care physician and patient adherence with CGA recommendations. MEASUREMENTS: Medical Outcomes Study Short Form-36 (MOS SF-36), restricted activity and bed days, Physical Performance Test, NIA lower-extremity battery. RESULTS: In complete case analysis (excluding the five control group subjects who died during the follow-up period), the adjusted difference in change scores (4.69 points) for physical functioning between treatment and control groups indicated a significant benefit of treatment (P = .021). Similar benefits were demonstrated for number of restricted activity days and MOS SF-36 energy/fatigue, social functioning, and physical health summary scales. In analyses assigning scores of 0 to those who died, these benefits were greater, and significant benefits for the Physical Performance Test and MOS SF-36 emotional/well being, pain, and mental health summary scales were also demonstrated. CONCLUSIONS: A single outpatient comprehensive geriatric assessment coupled with an adherence intervention can prevent functional and health-related quality-of-life decline among community-dwelling older persons who have specific geriatric conditions.

An in-home nurse-administered geriatric assessment for hypoalbuminemic older persons: development and preliminary experience.

BACKGROUND: Although malnutrition in older persons is a common, potentially treatable condition, few data indicate that treatments for this disorder can be effective. OBJECTIVE: To develop and preliminarily evaluate a two-component intervention that includes a nurse-administered, in-home assessment to identify potentially remediable causes of hypoalbuminemia and protocols to treat these problems. DESIGN: A pre-test post-test case-series. SETTING: An academic geriatrics practice. PARTICIPANTS: Seventeen persons aged 65 and older with serum albumin levels < or = 3.8 g/dL; eight of the participants received pre-and post-test outcome measures. INTERVENTION: Nurse-administered standardized assessment and intervention protocols. MEASUREMENTS: Serum albumin, Medical Outcome Study (MOS) SF-36, serum IL-1a and b, TNF alpha, IL-6, and lymphocyte markers of immune function. RESULTS: The assessment took 87 minutes, on average, and generated a mean 4.2 recommendations. Among the eight subjects with pre- and post-test measures, serum albumin increased by 0.2 g/dL (P = .035). Compared with baseline, two T cell markers of immune function demonstrated changes consistent with better function. CONCLUSIONS: These preliminary data support the potential benefit of a nurse-administered assessment coupled with protocols to address remediable contributors to hypoalbuminemia.

Geriatrics faculty in the United States: who are they and what are they doing?

Despite increases in geriatrics training at all levels of medical education, there is a nationwide shortage of geriatrics faculty. This shortage may be due in part to demands for clinical responsibilities that preclude adequate time for teaching and research. To learn about the professional activities of geriatrics faculty, we conducted a national survey of a 50% sample of all medical schools and their affiliated residency programs that focused on physician and non-physician geriatrics faculty in internal medicine, family practice, psychiatry, neurology, and physical medicine and rehabilitation. Although we found minor differences across specialties, in general, approximately one-third of physician faculty time is spent in teaching, the majority of which is clinical teaching. Less than 15% of physician faculty time is spent in research, and fewer than 10% of physician geriatrics faculty devote over half of their time to research. The percentage of time that non-physician faculty (other than "Research Only" faculty) spend in research is only slightly higher. These findings suggest that efforts to increase geriatrics education at all levels and promote research advances will be limited unless geriatricians devote substantially more of their time to these responsibilities.

Acceptability of mobile mammography among community-dwelling older women.

OBJECTIVE: To test the acceptability of mobile mammography among community-dwelling older women and to identify factors predictive of mobile mammography acceptance. DESIGN: Case series. SETTING: Twelve community meal sites sponsored by the City of Los Angeles Area on Aging. PARTICIPANTS: Two hundred fifty-five volunteers aged 60 to 84 years who attended community meal sites. INTERVENTION: On-site mammography offered to women who had not had a mammogram within the last year. MEASUREMENTS: Mammography acceptance rates, reasons for accepting or declining the mammogram, and breast cancer knowledge, beliefs, and intentions. MAIN RESULTS: One hundred seven of the 255 (42%) women were ineligible because they had received mammograms within the last year. Of the 148 women eligible, 57% accepted the mammograms and 43% declined; moreover, 20 of the 42 (48%) women who had not had a mammogram within the last 5 years or who never had a mammogram also accepted on-site mammography in the mobile van. Variables identified as predictive of mammogram acceptance included Asian American status, not being an HMO member, being married, a reported willingness to accept a screening mammogram if recommended by a physician, and previous mammogram screening history. CONCLUSION: Mobile mammography is acceptable to many older community-dwelling women. Although mobile mammography does not eliminate all barriers that inhibit a woman from receiving a mammogram, it may substantially increase screening for some groups.

The Prevention for Elderly Persons (PEP) Program: a model of municipal and academic partnership to meet the needs of older persons for preventive services.

OBJECTIVE: To create a program to identify preventive needs for community-dwelling older persons and incorporate intervention strategies to improve implementation of these services. DESIGN: Program development and case-series. SETTING: Community-based meal sites, academically administered program. PARTICIPANTS: Persons 60 years of age or older attending meal sites and their primary care physicians. MEASUREMENTS: Demographic characteristics, self reported preventive health behaviors and services, blood pressure measurement. RESULTS: During the first 2 years of the program, 927 persons 60 years of age or older were screened. The most common physician-initiated preventive recommendations were: tetanus booster (72%), aspirin prophylaxis (68%), pneumonia vaccination (61%), and colorectal cancer screening (51%). The most common self-care recommendations have been: calcium supplementation (54% of women) and breast self examinations (51% of women). As part of the adherence intervention, we were able to complete health educator calls for 600 (65%) subjects. In addition, the physicians of 599 (65%) subjects were contacted either by telephone (n = 496) or by letter only (n = 97). CONCLUSION: A community based preventive services program can identify large numbers of unmet preventive services needs, and a dual intervention strategy aimed at meeting these needs can be delivered successfully to the majority of participants. Implementation rates of specific recommendations and impacts on health outcomes remain to be determined.

The critical shortage of geriatrics faculty.

To estimate the adequacy of current and future supply of geriatrics faculty, we conducted a national survey to determine the current supply of geriatrics faculty in five specialties and compared these estimates to standards for optimal faculty supply in geriatrics. Finally, we generated a model to project future faculty supply based on both current training capacity and differing assumptions regarding future training capacity. Our findings indicate that the current supply of geriatrics physician faculty is less than half the number needed in each specialty. (Existing numbers range from a high of 909 faculty in internal medicine to a low of 86 in physical medicine.) Moreover, given the current capacity for training, there will be a net loss of such faculty each year in each specialty. We conclude that the number of geriatrics faculty currently available is insufficient to provide an appropriate "core" level of geriatrics training for all undergraduate medical students and residents in relevant residency programs. In addition, the current training capacity for geriatrics faculty cannot even sustain the current level of faculty over the next 10 years. To correct the current and future deficit, substantial increases in both geriatrics fellowship positions and mid-career training positions will be necessary.

How many physicians will be needed to provide medical care for older persons? Physician manpower needs for the twenty-first century.

To estimate the number of full-time-equivalent (FTE) physicians and geriatricians needed to provide medical care in the years 2000 to 2030, we developed utilization-based models of need for non-surgical physicians and need for geriatricians. Based on projected utilization, the number of FTE physicians required to care for the elderly will increase two- or threefold over the next 40 years. Alternate economic scenarios have very little effect on estimates of FTE physicians needed but exert large effects on the projected number of FTE geriatricians needed. We conclude that during the years 2000 to 2030, population growth will be the major factor determining the number of physicians needed to provide medicare care; economic forces will have a greater influence on the number of geriatricians needed.

Primary care of long-stay nursing home residents: approaches of three health maintenance organizations.

OBJECTIVE: To describe the innovative programs of three health maintenance organizations (HMOs) for providing primary care for long-stay nursing home (NH) residents and to compare this care with that of fee-for-service (FFS) residents at the same NHs. DESIGN: Cross-sectional interviews and case-studies, including retrospective chart reviews for 1 year. SETTING: The programs were based in 20 community-based nursing homes in three regions (East, West, Far West). PARTICIPANTS: Administrative and professional staff of HMOs in three regions and 20 NHs; 215 HMO and 187 FFS residents at these homes were studied. MAIN OUTCOME MEASURES: Emergency department (ED) and hospital utilization. RESULTS: All HMO programs utilized nurse practitioner/physician's assistants (NP/PA), but the structural configuration of physicians' (MD) practices differed substantially. At nursing homes within each region, all three HMO programs provided more total (MD plus NP/PA) visits per month than did FFS care (2.0 vs 1.1, 1.3 vs .6, and 1.4 vs .8 visits per month; all P < .05). The HMO that provided the most total visits had a significantly lower percentage of residents transferred to EDs (6% vs 16%, P = .048), fewer ED visits per resident (0.1 vs .4 per year, P = .027), and fewer hospitalizations per resident (0.1 vs .5 per year, P = .038) than FFS residents; these differences remained significant in multivariate analyses. However, the other two programs did not achieve the same benefits on healthcare utilization. CONCLUSIONS: HMO programs for NH residents provide more primary care and have the potential to reduce ED and hospital use compared with FFS care. However, not all programs have been associated with decreased ED and hospital utilization, perhaps because of differences in structure or implementation problems.

Life-sustaining treatment decisions for nursing home residents: who discusses, who decides and what is decided?

OBJECTIVE: To evaluate whether nursing home residents and their families reported discussions about life-sustaining treatment with their physicians, the relationship between such discussions and orders to limit therapy, and predictors of physician-patient communication about life-sustaining treatment. DESIGN: Cross-sectional interviews and retrospective chart abstraction. SETTING: Three regions: West Coast, New England, Western. SAMPLE: A total of 413 nursing home residents, 363 family/surrogate interviews, and 192 resident interviews. MAIN OUTCOME MEASURES: Measured were (1) physician-resident communication about life-sustaining treatment and (2) presence of an advance directive or do not resuscitate (DNR) order in resident's chart. RESULTS: Seventy-four percent of residents had DNR orders, and 32% had advance directives; only 29% of residents reported discussions about life-sustaining treatment. Of residents with DNR orders who could have participated in discussions about life-sustaining treatment, nearly half reported they had not discussed CPR with their caregivers. Older age, longer duration of time living in nursing home, location in a New England nursing home, physician-family member discussion, and the presence of an advance directive in the medical chart were positively associated with having DNR orders. Physician-resident discussion was not associated with having a DNR order. For the subsample of interviewed residents, age and a diagnosis of cognitive impairment were negatively associated with a physician-resident discussion about life-sustaining treatment, whereas the likelihood of having a discussion increased with increasing numbers of medical diagnoses. CONCLUSIONS: Chart orders to limit therapy are common, but physician-resident discussions about life-sustaining treatments are not. Far more family members than residents report such discussions with the resident's physicians.

Determinants of patient adherence to consultative comprehensive geriatric assessment recommendations.

BACKGROUND: In consultative models of Comprehensive Geriatric Assessment (CGA), lack of implementation of CGA recommendations is well documented and appears to be a potential explanation for negative findings. The purpose of this study is to identify patient determinants of adherence to recommendations received from a community-based CGA consultative model program. METHODS: Subjects (N = 139) received self-care and/or physician-initiated CGA recommendations and were interviewed three months later to determine adherence with the most important recommendation, and health belief, communication, and social support factors associated with adherence. Independent variables were organized into the Andersen Behavioral Model for analysis. RESULTS: At the bivariate level, one predisposing factor (intention) and six enabling factors (low difficulty level, high support, high utility, high self-efficacy, agreement on the importance of the recommendation and good specific communication about the recommendation) were significant determinants of adherence. Two functional health measures and seriousness of the target condition of the recommendation were significant need factors. In the final logistic regression model, one predisposing variable (intention), one enabling variable (utility), and one need factor (high functional status), and two interaction terms significantly predicted adherence. CONCLUSION: CGA recommendations that are seen as worthwhile, not too much trouble, and able to be accomplished are the most likely to be initiated. Older adults with relatively higher functional levels are also more likely to follow through with CGA recommendations even though their needs may be lower. We found the Andersen Behavioral Model useful in the analysis of factors associated with adherence behavior to consultative CGA recommendations.

Geriatrics in residency programs.

To determine how well geriatrics has been integrated into residency training, the authors surveyed a random 33% sample of all the 378 family practice (n = 126) and 420 internal medicine (n = 140) training programs in the United States in 1988. All the programs responded. On average, the internal medicine programs had more geriatrics faculty than did the family practice faculty, but these numbers were insufficient to meet current or future needs. Fewer than half of the residencies had geriatrics inpatient or ambulatory-care evaluation units, geriatrics consult services, geropsychiatry wards, or geriatrics clinics available as training sites. In contrast, nursing homes were available for 93% of the family practice programs and 58% of the internal medicine programs. A total of 80% of the family practice programs but only 36% of the internal medicine programs had geriatrics curricula in place. The authors conclude that integration of geriatrics content into residency training is far from universal, largely because of a shortage of faculty and clinical training sites.

Project Safety Net: a health screening outreach and assessment program.

Although comprehensive geriatric assessment (CGA) has been conducted in many settings, its use in community-based outreach programs has been limited. We have developed Project Safety Net, a program that identifies low-income urban-dwelling frail elderly persons and provides CGA and appropriate referral. The program uses validated screening instruments and makes extensive use of a custom-designed computer program to provide information to the interdisciplinary team and for research purposes. During an 8 month period, 814 older persons were screened including high proportions who were widowed (51%) and who lived alone (66%). The effectiveness of this program remains to be determined in a randomized clinical trial.

Preventive health behaviors and mammography use among urban older women.

A cross-sectional survey of 610 low income women between the ages of 60 and 84 who attended community meal sites in Los Angeles was conducted to determine health behaviors associated with mammography use among urban community dwellers. Preventive practices that require women to take an active role and recurrent participation were positively associated with a current mammography, while services that are clinician-initiated were associated with ever having a mammography.

Enrolling community physicians and their patients in a study of prevention in the elderly.

Enrollment of senior citizens in a community Medicare demonstration project to explore the efficacy of preventive health screening and health education was accomplished by using a two-stage process. This process consisted of initial communication with community physicians through the University of California at Los Angeles Clinical Faculty Association to establish credibility for the program. Physicians who agreed to participate then selected potential participants to receive, by mail, a description of the study and an introductory letter from their own physician. Followup and actual enrollment of participants was then handled by the study team. A total of 57.6 percent of the elderly people approached agreed to participate in the study.

Predictors of medication prescription in nursing homes.

OBJECTIVES: To identify patient characteristics associated with higher numbers of prescribed drugs or risk of receiving one or more inappropriate medications. DESIGN: A cross-sectional survey using chart reviews. PARTICIPANTS: A total of 414 long-stay residents of 20 nursing homes in three states MEASUREMENTS: Current medication orders, sociodemographic information, and diagnoses and health status information as indicated by the MDS. The number of routine, total, and inappropriate medications were tabulated. RESULTS: Higher numbers of medications were associated with higher total numbers of diseases. In addition, several diseases (congestive heart failure, hypertension, depression, anxiety, and diabetes) were associated with higher numbers of medications even after controlling for total disease burden. Cognitive impairment was associated with fewer medications after controlling for total number of diseases. Advanced age also attenuated the effect of disease burden on the number of total and routine medications. The only independent predictor of more inappropriate medications was higher numbers of routine medications. CONCLUSION: Several specific disease states predispose patients to prescription of higher numbers of medication, and, these patients must be managed more carefully to prevent adverse drug-drug or drug-disease interactions. Why patients with compromised cognitive status receive fewer medications requires further study.
